Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Excalidraw

  • Advanced features (unlimited private scenes/folders, cloud storage, access management, presentations, extended AI, team management) are gated behind Excalidraw+
  • Free hosted version persists via scene links/local storage rather than a managed multi-scene workspace
  • Self-hosting the full collaborative stack requires standing up a websocket server and storage beyond the npm editor package
  • No official native desktop or app-store mobile apps - web/PWA only

Postgres

  • Each major version is supported for only 5 years after its initial release, after which it is end-of-life
  • Major version upgrades break on-disk compatibility and require a full dump and reload or the pg_upgrade tool
  • New major versions ship about once a year, so staying supported means a disruptive upgrade cycle
  • Minor releases contain only frequently-encountered bug fixes, low-risk fixes, security issues and data corruption fixes, so feature gaps are not addressed within a major version
  • There is no vendor SLA; commercial support must be bought separately from third party professional services listed by the project
